 short. Drupe dry, 1 -seeded, marked with 8 fur- 

 rows. 



Trees or shrubs; flovers axillary, solitarv or ag-grei^ate, 

 sometimes polygamotis. In :he E. angustifolia, culuyated 

 in Europe and Africa, fvH- the fine odor of its flov.ers, ihe

Species. 1. E.*argentea. Unarmed; leaves undulated, 

 oval oblong-, rather acute, on either side smooth, and co-

11 AB. At Hudson's Bay, and on the arg-illaceous brokea 

 banks of tlie Missouri, near Fort Mandan. \ shrub from 

 8 to 12 feet hig^h, appar< ntly dioicous, producing a dry 

 farinaceous edible drupe, about the size of a small 

 ciierry. 



This genus is so nearly allied to Hippophae^ as well as to 

 another which I am about ti) propose, that it is to be re- 

 gretied any artificial sy.-tem snould ever separate them. 

 They are, iiowever, distinctly dioicous, having male and 

 female fiov^ers of different structure. Of this genus, be- 

 sides the above, (which appears to be more nearly related 

 to the E. macropliylla of Japan, than ihe E. latifolia) yih^.re 

 are 10 species; 1 m the South of Kurope, another in Rus- 

 sia aiul the Kasr, another in Kgypt, and a 4th m Ceylon, 

 with 6 in Japan.
